Why not drink old tea?

Because the old tea head is the leftover of cooked tea, there may be impurities in the stuck tea balls, and its own sanitary condition cannot be guaranteed, so the old tea head can't be drunk. Old tea head is pectin secreted by Pu 'er cooked tea when it is piled up and fermented at high temperature and high heat. Tea leaves with thick pectin coagulate into tea bumps during continuous stirring. After the fermentation is completed, break the caked tea bumps by hand and put them into the tea pile. Too sticky tea blocks, afraid of breaking the tea leaves in the process of breaking, are picked out separately and become tea bumps, which is what we call old tea heads. \x0d\ For more information about why you don't drink old tea, please visit:/ask/2b03801615823123.html?
